Here is the correct order of events from the production of a “sound” from an instrument to your listening pleasure:
A-minor chord
Alternate waves of air pressure are created
Auditory meatus funnels air pressure waves
Tympanic membrane vibrates
Auditory ossicles move and amplify
Stapes transfers motion to oval window
Pressure wave moves through perilymph in scala vestibuli of cochlea
Basilar membrane resonates
Spiral Organ of Corti moves up and down
Hair cell stereocilia deform and bend
Action potentials are generated
Cochlear nerve sends action potentials to brain
Auditory area of temporal cortex is stimulated
Sigh, good tunes
